Abstract

Fatty acids and mineral elements of the seeds of Elaeagnus conferta Roxb. were examined. The yield of seed oil was 1.98%. The main components were oleic acid (C18:1,34.15%),linoleic acid (C18:2,31.51%),palmitc acid (C16:0,13.83%) and stearic acid (C18:0,2.88%). The ratio of saturated fatty acids : monounsaturated fatty acids : polyunsaturated fatty acids was 1:2.23:2.71. The contents of mineral elements were as follows,7 837.69 mg kg-1 for K,30.99 mg kg-1 for Fe,10.13 mg kg-1 for Zn and 259.5 mg kg-1 for Na.
